Brembo 19+ 330i Rear GT BBK 4 Piston Cast 380x28 2pc Rotor Slotted Type1-White

This is the Brembo GT Big Brake Kit for the rear of your 2019 and newer BMW 330i. It's a comprehensive upgrade designed to significantly improve your car's braking performance, especially under demanding conditions. The kit includes everything you need to swap out your stock rear brakes for a much more capable setup, featuring four-piston calipers and larger two-piece rotors.

At the heart of this kit are the Brembo GT calipers, which are cast from aluminum for a good balance of strength and light weight. They house four pistons, providing more clamping force than most factory calipers, which translates to better stopping power and feel. The rotors are a substantial 380mm in diameter and 28mm thick, offering increased thermal mass to resist fade during repeated hard stops. These are two-piece rotors, meaning the hat is a separate piece from the friction ring, which helps manage heat and can make replacement easier down the line. The rotor faces are slotted with Brembo's Type 1 pattern, which helps to vent gases and dust away from the pad surface, maintaining consistent braking performance. The kit comes with white calipers and the specified slotted rotors.

When installing a big brake kit like this, it's important to ensure you have the right tools and follow the manufacturer's instructions carefully. This kit is a significant upgrade, and it's designed to work with your vehicle's existing ABS and stability control systems. You'll notice a substantial difference in pedal feel and stopping distance, particularly when driving spiritedly or on a track. This kit is a solid option if you're looking to maximize your 330i's braking capability.
